Answer: 147
Step-by-step explanation:
3 * 9 = 27 so the last digit is 7 and the 2 carries. 3 * 4 = 12 but because we carried the 2, we get the first two digits are 14.
Therefore the value inside the green box is 147. If we wanted to find the next gray box, we'd use the same process but multiply the 4 from 43. The last gray box is the sum of the two numbers.
